The range for the changeable AO settings is 0.000mA to 3.750mA. The change step is 0.025mA. Please note the HART
communication may not work reliably if the current level is set to below 1.25mA.
4.4.2 Relay Zone - Horn Mode
Horn mode is designed to allow local acknowledgment of a relay-triggered horn, while the alarm state is still present. All alarms
on both sensors trigger both relays, however the second relay can be acknowledged over Modbus/Bluetooth/HART.
4.4.3 Unit Device ID/Tag
This is device tag/name used to identify the unit during HART and Bluetooth communication. Default is “GM_S5K_0 “. Users
can change this string to any characters from the following character set. The string length is limited to eight characters.
4.4.4 Alarm Direction
Relays can be triggered by an alarm threshold as gas readings increase or decrease. Most applications require increasing
alarm thresholds, except for Oxygen monitoring, which is most often a decreasing alarm.
The default alarm direction for Oxygen sensor is decreasing, or downward.
The default alarm direction for all other sensors is increasing, or upward.
